The Chinese in California, 1850-1925 illustrates nineteenth and early twentieth century Chinese immigration to California through about 8,000 images and pages of primary source materials. Included are photographs, original art, cartoons and other illustrations; letters, excerpts from diaries, business records, and legal documents; as well as pamphlets, broadsides, speeches, sheet music, and other printed matter. These documents describe the experiences of Chinese immigrants in California, including the nature of inter-ethnic tensions. They also document the specific contributions of Chinese immigrants to commerce and business, architecture and art, agriculture and other industries, and cultural and social life in California. Chinatown in San Francisco receives special treatment as the oldest and largest community of Chinese in the United States.
